Go with the paddles, here is a copy of my post from a few months ago showing how to deal with your concerns.
I have worked on making the NEW chat adapter fit the berserker, I have drawn an image of what I did with a description ... hope its enough ....

If you take care, the paddles still look perfect ..... take care when creating the concaved area on the adapter not to expose the innards (very gently does it !!!)
I used a Dremel stylus modelling tool with a small sander attachment, not difficult, but care MUST be taken to avoid removing too much material.
It now fits and works perfectly, paddles look untouched and original .....
This my solution to the issue, you may have your own, PM me if you need more info ....
